Pathophys a useful pre-CRNA course?

My CCRN is tomorrow! Very anxious despite 6+ weeks of dedicated studying.

You won't believe this! The testing center completely screwed up and gave me some BS story about how they're moving soon (but they don't know where or when) and thus they don't have an intact phone linefor the computer. This wasn't discovered until I sat down to take the test. I was livid! All that studying and anxiety. Worst is I have no idea of when I CAN take it - AMP and AACN are still playing games. I am so ******.

I'm hoping to be accepted this year, but in case I'm not I'm making plans to strengthen my app for next year. One strategy is to take a graduate course in pathophys at the state university where I got my BSN. It's designed for their nursing grad students - the school has NP and CNS programs. Obviously it's not aimed at anesthesia in particular, and I don't think it will substitute for any course I might have to take in CRNA school, but it seems like it would be a good science base to have as well as proving I can handle graduate-level coursework. My employer will pay if I get B or better.

Good plan? Waste of time and energy? Any other ideas? I'm also taking the CCRN tomorrow and will take another graduate summer course if I don't get in. Maybe will go work in our SICU/CTICU although I don't want to, I love my medical unit. But the hearts experience would look good.
